Brick Pointing & Mortar Design

Mortar Mix Designs

Brick Pointing, or Repointing, pertains to the installation and subsequent re-application of  various mortar mixes. These mortar mixes may be Lime-based (limestone/ calcium carbonate – CaCOˆ3) or cement-based; created from furnace or steel slag (portland cement- pictured above). Traditional mortar mixes also include clay and aggregates, sands and other organic materials like seashells or unslaked-limestone fragments.

Pointing (Mortar Joint) Styles

Shag Pointing, otherwise known as ‘Cottage Shag’ is really the first and original tamp or tuck point. Installed by a well-timed process, the lime-based mortar was tamped or pressed into the joint by way of brush or pieces of timber. Shag pointing was used to create texture and help to further define the already rustic nature of the masonry unit.

Flush Pointing has the mortar joint finish slightly behind the arris, or edge, or the brick or block. This is also known as struck mortar joints.

Brick Tuckpointing, entails matching the colour or texture of the masonry unit in order to then strike lime used to create a more uniform and formal finish.

Ribbon Pointing, is a method to bring back brick to original; as opposed to the brick tuck pointing method shown above. Ribbon pointing reinstates a deeper joint therefore outperforming brick tuck point insofar as durability, or service life, is concerned.


Ribbon pointing is also used to straighten walls. The joint pictured is up to four inches deep. This is then followed by colour-matched mortar repair.
